Summary: I got this to project images onto canvas for sketching prior to painting. Trying to plug into my MacPro laptop was futile. I never found a way to get to the images. I ended up transferring the images to a USB drive then plug that into the projector.
Excerpt: Compact-check Bright-check Cute-Check With single USB port it is not possible to present from flash drive and access WI-FI with (optional) dongle; so still married to laptop for one or the other. Internet surfing is virtually impossible with the "virtual keyboard" feature-terrible interface !
Summary: Love the size and the projected clarity is plenty good. My issue with it is that it's not plug-n-play. It would not paginate a pdf file off a thumb drive (as advertised) and their tech support couldn't resolve.

Summary: I can see why people rave about this little wonder...in the first few hours of operation, the picture was bright and clear, even at 84" diagonal. Sadly, within the space of 10 hours, it's brightness diminished substantially, and the focus, even after the "warm-up" time required, just didn't cut...
Summary: Good Afternoon, I bought a projector Qumi Q5 few months ago and used it 3 or 4 times. Today I went to use the projector for a business presentation and noticed some black spots in the projected image. Then these small black spots began to multiply the screen and soon were taking the whole image.
